Sclerotomy in uveal effusion syndrome

PURPOSE: To report visual and anatomic outcomes after modified scleral surgery in patients with uveal effusion syndrome with retinal and choroidal detachment. METHODS: In five eyes of four patients with retinal and choroidal detachment and uveal effusion syndrome due to nanophthalmos, we performed pars plana full-thickness unsutured sclerotomies without sclerectomy. RESULTS: In all cases, uveal effusion with choroidal and retinal detachment resolved within 3 weeks, and all patients showed improved vision. The functional and anatomic results remained stable for over 2 years. CONCLUSIONS: Uveal effusion syndrome that is refractory to medical treatment (high-dose systemic corticosteroids) can be managed effectively by pars plana full-thickness unsutured sclerotomy without sclerectomy.     

Treatment of glaucoma in young nanophthalmic patients

Purpose: To evaluate the criteria of diagnosis and management of secondary glaucoma in young nanophthalmic patients. Methods: Considering the anatomic features and clinical characteristics, 22 eyes of 11 patients were identified as bilateral nanophthalmos. Intraocular pressures (IOP) were checked with Goldmann applanation or Keeler pulse-air 2000 tonometer, and Nd-Yag laser was used for iridotomies. Prophylactic V-shaped unsutured sclerectomies over the pars plana were combined with trabeculectomy, and Mitomycin C (MMC) in 0.2 mg/ml concentration was applied. Results: Among 22 eyes of bilateral nanophthalmic patients 8 eyes had secondary angle-closure glaucoma. Laser iridotomies were performed in 6 eyes. Laser iridotomy and supplemental medical therapy were sufficient in 4 out of 6 eyes. Mean IOP dropped from 26.4 to 14.5 mmHg in these patients. Due to continuous increase of IOP in the other patients, they underwent trabeculectomy with V-shaped sclerostomy and intraoperative MMC application. Mean IOP dropped from 39.3 mmHg to 19.3 mmHg. Postoperative uveal effusion or other major complications were not observed. Mean age of these patients was 14.6 years during treatment. Conclusion: Management of glaucoma in nanophthalmus is complicated. Initial treatment is medical. If it is insufficient, laser iridotomies and V-shaped sclerostomies with filtration surgery can be performed at any age.     

The Management of Secondary Glaucoma in Nanophthalmic Patients

Purpose:To investigate the clinical characteristcs,management of secondary glaucoma in nanophthalmos,and the prevention of its compications.Methods:Retrospectively,9 cases(17eyes)with nanophthalmic glaucoma were studied.Results:The axial length of the eyes ranged(14.36-19.33)mm;All of the cases combined with hyperopia ranged( 7.00- 16.00)D.All 17 eyes had the manifestation like angle-closure glaucoma.The glaucoma was controlled in 9 of 17 eyes at the early stage,which underwent laser iridotomy(4 of 9 eyes also underwent laser iridoplasty).1 eye underwent ciliary photocoagulation because its visual acuity was lost and the patient complained of pain.The other 7 eyes underwent filtration surgery and 3 of them had permanent loss of vision caused by disastrous complications after the surgery.Conclusions:Management of secondary glaucoma in nanophthalmos is complicated.The laser iris surgery is safe and effective in glaucoma at the early stage.Vortex vein decompression,sclerotectomy or anterior sclerotomy may be performed to reduce disastrous complications.     

Full-thickness Sclerotomy for Uveal Effusion Syndrome

To report the surgical outcome of full-thickness sclerotomy in five cases of uveal effusion syndrome (UES). Full-thickness sclerotomy without sclerectomy was performed on five eyes of four patients with UES with or without nanophthalmos. In four of the eyes, exudative retinal detachment associated with UES resolved after the sclerotomy. The subretinal fluid in one eye, which had a normal axial length, was relieved after undergoing three sclerotomy procedures. Full-thickness sclerotomy without vortex vein decompression or sclerectomy is an effective surgical option for the management of significant UES.

Nanophthalmos: A Perspective on Identification and Therapy

Nanophthalmos is a rare and blinding disease. Diagnostic features include a small eye, small cornea, shallow anterior chamber, narrow angle, high lens/eye volume ratio, and uveal effusion. Intraocular surgery has a high rate of disastrous complications and blindness. The 32 eyes (16 patients) presented are in three categories based on angle closure and intraocular pressure levels. Treatment methods included medication, laser iridotomy and gonioplasty, peripheral iridectomy, filtration surgery, and cataract extraction. Glaucoma medication was effective, although miotics sometimes increased pupillary block. Laser iridotomy was successful in 83% of six eyes; laser gonioplasty in 91.6% of 12 eyes. Peripheral iridectomy succeeded in two of seven eyes, and filtering operations provided tension control in two of five eyes. Thirteen of 15 eyes undergoing filtration surgery suffered severe postoperative visual loss. Cataract extraction improved vision in only three of six eyes. The authors’ experience confirms that surgery in nanophthalmic eyes has an extremely high complication rate with disastrous results. Medication and laser therapy are the procedures of choice for angle-closure glaucoma in nanophthalmos.     

Two cases of uveal effusion syndrome

PURPOSE: To report a case of uveal effusion syndrome associated with hypotony and a case of uveal effusion syndrome in nanophthalmos. METHODS: The first case was a 25-year-old man who presented with decreased visual acuity in the left eye and hypotony. Fundus examination revealed choroidal effusion and retinal detachment with a thickened eyeball. Partial thickness sclerotomy and sclerectomy were performed. The second case was a 13-year-old boy who had uveal effusion syndrome with a nanophthalmic eye. RESULTS: In the patient with hypotony, intraocular pressure was well maintained following partial thickness sclerotomy and sclerectomy, and choroidal effusion and retinal detachment were reduced. The visual acuity of the nanophthalmic patient was well maintained during a 3-year follow-up period without treatment. CONCLUSIONS: appropriate treatment modalities should be considered depending on the ophthalmic condition of the individual patient.     

Nanophthalmos with longstanding choroidal effusion and serous retinal detachment

Purpose: To report a typical case of nanophthalmos with uveal effusion and local serous retinal detachment followed for 1 year. Methods: Clinical ocular examinations included vision, refraction, corneal diameter; anterior chamber depth, intraocular pressure, fundoscopy, A/B scan ultrasonography and gonioscopy. Results: Both eyes were hypermetropic with small corneas and shallow anterior chambers. Decreased axial length and thickened sclera were also found. There were peripheral choroidal effusions and local serous retinal detachments as well. The patient declined any surgery that was offered. No significant change in either eye was found after I year follow-up. Conclusion: This case illustrates that the progress of choroidal effusion and retinal detachment in nanophthalmos may be very slow and even non-progressive for at least 1 year. In these cases sclerectomy and or sclerotomy may be delayed without undue immediate risk to the vision.     

Nanophthalmos in sisters, one with exfoliation syndrome

In a consanguineous family of two siblings, both with nanophthalmos, one was found to also have bilateral exfoliation syndrome. This combination of conditions has not, to our knowledge, previously been reported and has not had any apparent negative consequences. Her sister has manifested typical complications of nanophthalmos, including angle-closure glaucoma initially and, eventually, severe uveal effusion after cataract surgery.

Management of glaucoma in patients with nanophthalmos

AIMS: In this retrospective study, we aimed to evaluate the results of glaucoma surgery in patients with nanophthalmos. METHODS: Twenty-eight bilateral nanophthalmic patients, of whom 20 patients underwent trabeculectomy+Mitomycin-C (MMC)+inferior sclerotomy between 1996 and 2004, were included in this study. Records of patients with nanophthalmos were reviewed. Intraocular pressure (IOP), glaucoma medications, surgical success, visual acuity and complications were analyzed. RESULTS: The mean IOP was 34.6+/-5.3 mm Hg preoperatively. At the final follow-up visit, the mean IOP dropped to 21.41+/-7.34 mm Hg (P<0.05). The cumulative probability of success was 85% at 1 year, 78.5% at 2 years, 76.9% at 3 years, 70.6% at 4 years and 47% at 5 years after surgery. Visual acuity decreased in 13 (65%) patients but no eye lost vision. Sequels of choroidal detachment (five patients 25%) and retinal folds (four patients 20%) were the most frequent reason for visual decrease. Uveal effusion (10 patients 50%) and cataract formation (seven patients 35%) were major late postoperative complications. CONCLUSIONS: Results indicate that trabeculectomy+MMC+inferior sclerotomy procedure was effective and safe for glaucoma control in patients with nanophthalmos, but uveal effusion is a major problem and cataract surgery is expected in the long run.     

Cataract surgery in patients with nanophthalmos: results and complications

PURPOSE: To evaluate the results and complications of cataract surgery in patients with nanophthalmos. SETTING: University hospital practice. METHODS: The records of consecutive patients with nanophthalmos who had cataract surgery from 1978 through 2002 were reviewed for ocular diagnoses, corneal diameter, keratometry, axial length, retinal-choroidal-scleral thickness determined by echography, ocular surgeries, visual acuity, and complications. RESULTS: Eight patients (6 women, 2 men) with a mean age of 59 years were reviewed. Four patients were not previously diagnosed with nanophthalmos; increased retinal-choroidal-scleral thickness (mean 2.41 mm) confirmed the diagnosis. Twelve eyes had cataract extraction with posterior chamber intraocular lens (IOL) implantation, 11 by phacoemulsification and 1 by extracapsular cataract extraction, and 4 eyes had lamellar scleral resections. Additional surgeries included glaucoma laser treatment (8 eyes), cyclocryotherapy (2 eyes), trabeculectomy with scleral resection (1 eye), trabeculectomy combined with phacoemulsification (1 eye), and neodymium:YAG laser capsulotomy (4 eyes). No eye lost vision; however, complications included severe iritis, broken IOL haptic with vitreous loss, posterior capsule opacity, choroidal hemorrhage, phthisis, and aqueous misdirection. CONCLUSIONS: Results indicate that echography should be used to assess retinal-choroidal-scleral thickness in eyes that are hyperopic and at risk for narrow-angle glaucoma. Thickening may confirm the diagnosis of nanophthalmos and allow careful preoperative assessment and appropriate operative procedures in these high-risk eyes. With advances in cataract, glaucoma, and uveal effusion treatments, surgical results in patients with nanophthalmos are improving.     

Non-penetrating deep sclerectomy for glaucoma associated with Sturge-Weber syndrome

PURPOSE: To report the results of non-penetrating deep sclerectomy (NPDS) in the treatment of glaucoma associated with Sturge-Weber syndrome (SWS). METHODS: We carried out a retrospective case series analysis of patients who underwent NPDS for glaucoma associated with SWS between 1998 and 2003. The control of glaucoma after NPDS, the results of surgery on intraocular pressure, the need for additional medical treatment and surgical complications were studied. RESULTS: Twelve eyes of nine patients, aged 11 days to 24 years, underwent filtering surgery: nine NPDS procedures were performed and three surgical procedures had to be converted to trabeculectomy because NPDS was not technically achievable. The mean follow-up after surgery was 26.3 months (range 6-48 months). Two trabeculectomies were complicated by choroidal effusion, which resolved in both cases. Good control of glaucoma was obtained during follow-up. CONCLUSIONS: Non-penetrating deep sclerectomy is transiently efficient in the treatment of SWS-associated glaucoma. Further studies of NPDS for the treatment of glaucoma associated with SWS are warranted.

Dilated episcleral veins with secondary open angle glaucoma

We report a case of dilated episcleral vein with secondary open angle glaucoma. A 65-year-old female presented with redness of both the eyes without any prior systemic history. Her ocular examination revealed dilated episcleral veins and a high intraocular pressure (IOP) of 38 mm Hg in the right eye. Systemic examination was negative for carotid cavernous fistula, low-grade dural arteriovenous fistula, dysthyroid ophthalmopathy, and primary pulmonary hypertension. During follow-up, her IOP remained in high thirties despite maximum medications. She underwent right eye trabeculectomy with partial thickness sclerectomy with sclerotomy. In the beginning, the sclerotomy incision was not deepened into the suprachoroidal space. She developed choroidal effusion during surgery and the sclerotomy was deepened into suprachoroidal space and straw color fluid was drained. Postoperatively, she developed choroidal effusion, which resolved with conservative management. This case highlights the importance of sclerotomy in such cases of high episcleral venous pressure.     

Uveal effusion and angle-closure glaucoma in primary pulmonary hypertension

PURPOSE: To report a patient with uveal effusion and intermittent angle-closure glaucoma associated with primary pulmonary hypertension. METHODS: Observational case report. RESULTS: A 78-year-old woman with primary pulmonary hypertension noticed pain and decreased vision in her right eye. Ocular examination disclosed excessive dilation of conjunctival and episcleral veins and uveal effusion with annular ciliochoroidal detachment in both eyes. The right eye revealed corneal edema with folds in the Descemet membrane, congested iris vessels, and a markedly shallow anterior chamber with a partially closed angle, corresponding to a recent attack of angle-closure glaucoma. Systemic treatment of her congestive heart failure with an angiotensin-II receptor antagonist resulted in a partial resolution of the uveal effusion and complete normalization of the anterior chamber depth. CONCLUSION: Primary pulmonary hypertension may cause uveal effusion, leading to a forward displacement of the lens-iris diaphragm and intermittent angle-closure glaucoma.     

Angle-closure Glaucoma: The Role of the Lens in the Pathogenesis, Prevention, and Treatment

Primary angle-closure glaucoma is a major cause of blindness worldwide. It is a disease of ocular anatomy that is related to pupillary-block and angle-crowding mechanisms of filtration angle closure. Eyes at increased risk for primary angle-closure are small with decreased axial length, anterior chamber depth, and filtration angle width, associated with a proportionately large lens. Angle-closure glaucoma afflicts Asian and Eskimo eyes more frequently than eyes in other races with similar predisposing dimensions. The treatment of primary angle closure addresses its causal mechanisms. Laser peripheral iridotomy equalizes the anterior and posterior pressures and widens the filtration angle by reducing the effect of pupillary block. Argon laser peripheral iridoplasty contracts the iris stroma to reduce angle crowding and is helpful for some affected eyes. Lensectomy dramatically widens the angle and eliminates pupillary block. Clinical reports of lensectomy with posterior chamber intraocular lens implantation in the treatment of acute, chronic, and secondary angle-closure glaucoma describe very favorable results. The appropriate role for lensectomy in the management of primary angle closure, however, remains unproven. Prospective, randomized clinical trials are ongoing to determine the value and comparative risks and efficacy of lensectomy versus medical therapy, laser peripheral iridotomy, laser iridoplasty, and filtration procedures for the treatment of acute and chronic primary angle closure and for the prevention of chronic angle-closure glaucoma, both after and in place of laser peripheral iridotomy.     

Uveal melanoma presenting as acute angle-closure glaucoma: report of two cases

PURPOSE: To present two cases of uveal melanoma presenting as acute angle-closure glaucoma. DESIGN: Observational case reports.Assessment and management of two patients with uveal melanoma presenting with acute angle-closure glaucoma. RESULTS: One patient was initially treated with antiglaucoma medications, and a laser peripheral iridotomy was performed. The second patient had opaque media preventing visualization of the posterior segment, but the presence of an occult mass was suspected as the cause of angle closure. In both cases, B-scan ultrasonography revealed the presence of a tumor causing angle-closure glaucoma. The eyes were enucleated, and the diagnosis of uveal malignant melanoma was confirmed by histopathology. CONCLUSION: Although acute angle-closure as the initial presentation of uveal melanoma is rare, the presence of a uveal melanoma should be suspected in eyes unresponsive to medical therapy, especially in unilateral cases in which the view of the posterior segment is obscured.     

A case of acute angle-closure glaucoma secondary to annular ciliochoroidal detachment after unsutured cataract surgery

BACKGROUND: We report a patient with acute angle-closure glaucoma secondary to annular ciliochoroidal detachment after unsutured cataract surgery. CASE: An 82-year-old man was diagnosed with bilateral shallow central anterior chamber depth, flat peripheral anterior chamber, and elevated intraocular pressure. One day previously he had undergone uncomplicated unsutured cataract surgery in the right eye and eight days previously, in the left eye. Ultrasound biomicroscopy revealed annular ciliochoroidal detachment in both eyes. Treatment with intravenous methyl prednisolone deepened the anterior chamber and reduced intraocular pressure. CONCLUSION: Annular ciliochoroidal detachment may lead to anterior rotation of the ciliary body and angle-closure. This clinical entity is indistinguishable from malignant glaucoma when the fundus cannot be visualized.
