Características clínicas y análisis de OCT de una serie de casos de microftalmos posterior

Posterior microphthalmos is a rare condition that can be found in paediatric patients with increased farsightedness and reduced vision. A retrospective study is presented of 5 cases of posterior microphthalmia aged between 4 and 13 years. The following parameters were obtained: visual acuity, cycloplegic refractive error, optical biometry, slit lamp examination, intraocular pressure, and ocular ultrasound. The refraction, axial length and average visual acuity was + 15.35 Dp, 16.20 mm and 0.13, respectively. The fundus was examined, optical coherence tomography was performed, and also retinography and fluorescein angiography in one case. In all cases, the absence of foveal depression and different morphotypes of the papillo-macular fold were observed in the tomography. In the absence of a specific treatment, the appropriate detection, management, and monitoring of this disease is important to improve and maintain the vision of patients and recognise possible complications.     

Síndrome de Straatsma: tratamiento satisfactorio de ambliopía.Reporte de 2 casos

Clinical cases

The cases are presented on 2 female patients with Straatsma syndrome, with satisfactory treatment of amblyopia.

Presentación atípica de la enfermedad de Best

Clinical case

A 43-year-old man was treated for reduced visual acuity, initially attributed to strabismic amblyopia. On fundus examination, bilateral neurosensory detachments (NSD) were observed in posterior pole, surrounded by deposits of lipofuscin. His 3-year-old son was also examined and circumscribed NSD was observed with the presence of pseudohypopyon in OD and a fibrosis scar in OS. The Arden ratio were decreased in electrooculography (EOG) in both patients, and genetic studies revealed a single mutation of the BEST1 gene.

Eficacia y complicaciones de las transposiciones musculares en el síndrome de Duane con esotropía

ObjectiveTo study the long-term efficacy and the complications of several transposition techniques for the treatment of Duane syndrome. These included, full vertical rectus transposition, partial vertical rectus transposition, transposition without muscle disinsertion, and superior rectus transposition.Material and methodsA retrospective study of the patients diagnosed with Duane syndrome, and who underwent any of the different transposition techniques associated or not to the medial rectus recession with a follow-up longer than 12 months. A good result was considered a final deviation ≤ 10 prism dioptres (pd) in primary position, anomalous head posture < 10°, and an improvement of the abduction without diplopia.ResultsSeven cases were included (6 women, 6 unilateral), and a mean age of 37.71 years. Pre-operative central gaze esotropia of 28 ± 11.68 pd decreased to 6 ± 4.62 pd at the final visit (P = .009). The anomalous head posture decreased in 6 patients, and the abduction improved one degree from ?3.14 to ?2.14 (mean). An induced vertical deviation ≤ 8 pd was observed in 4 cases. None experienced diplopia at the final visit. The percentage of reoperations was 71.42%. Only 28.57% had a favourable outcome with a single surgery, which increased to 71.42% with further surgeries at the final follow-up. Mean evolution time was 52 ± 31.65 months.ConclusionsVertical rectus transpositions in Duane syndrome with moderate or severe clinical signs have only been effective in a small percentage of the cases. Most of them required further surgeries to resolve the complications or the under-corrections.     

Alteraciones de la motilidad ocular en el síndrome de Kabuki

Kabuki syndrome is a rare genetic disorder, caused by mutation in the KMT2D or KDM6A genes, which affects several organs in the majority of patients, among which are the eyes. The most typical clinical characteristics are mental retardation, postnatal growth retardation, skeletal anomalies, and characteristic facial features. As the eyes are affected in most of the cases, ophthalmological examination is recommended for the early detection of ocular anomalies, in order to prevent visual impairment. The most frequent ocular signs are strabismus, ptosis, and refractive anomalies. A series of cases of Kabuki syndrome is described in five children, four of whom exhibited strabismus with esotropia, over action of inferior oblique muscles, and under action of superior oblique muscles associated with a V pattern. Most published papers do not report or might underestimate the ocular problems.It may be appropriate to perform orbital magnetic resonances in order to detect changes in the muscle paths that are related to the pathology of the eye movements found.     

Agujero macular iatrogéno durante la inyección de perfluorocarbono líquido en una cirugía de desprendimiento de retina

To describe a macular hole development during intravitreal injection of perfluorocarbon liquid used to repair a rhegmatogenous retinal detachment.Clinical caseA 73-year-old man presented with superotemporal rhegmatogenous retinal detachment. During surgery, along the perflorocarbon liquid injection, a full thickness macular developed and perfluorocarbon was accumulated in subretinal space. Perfluorocarbon liquid was then extracted through the macular hole. Postoperatively, ocular coherence tomography confirmed the existence of a full-thickness macular hole. One month later, this macular hole was successfully treated with the use of an inverted internal limiting membrane flap.Intravitreous liquid PFC injection is a resource to aid in subretinal fluid exit. A number of complications, both intra and postoperative, have been associated with the use of PFC. This is the first reported case of a complete macular hole secondary to PFC injection.     

Coriorretinopatía serosa central de etiología inusual: a propósito de dos casos

ObjectiveDescribe 2 rare causes of central serous chorioretinopathy.Clinical casesCase 1: A 35 year old woman with loss of vision in her left eye, with a recent history of a flu vaccination. This could have been the process that triggered an immune response, with increased circulating immune complexes that favour choroidal ischemia.Case 2A 41 year old man with loss of vision in his left eye. As history, had consumed cocaine, which could be related to its adrenergic effect adrenergic, and earlier excimer laser refractive surgery (LASIK).ConclusionIn both cases there was a temporal relationship between cause and effect.     

Experiencia a largo plazo de pacientes con anomalía de Peters

PurposeTo report the results in a series of Peters Anomaly cases, and propose management and treatment approaches according to the alterations associated with each case.Material and methodsA retrospective analysis was performed on the records of 27 patients (32 eyes) clinically diagnosed with Peters Anomaly. Each patient was subjected to different treatment modalities according to the type of Peters Anomaly, anywhere from medical follow-up clinics to a Penetrating Keratoplasty procedure (PKP).ResultsOf the 27 patients (32 eyes), 74% were male and 26% female, with 18.5% (5) being bilateral and 81.5% (22) unilateral. The mean number of years of follow-up was 10.2 years (Range: 3.5 to 18 years). The results of long-term VA correlate directly with the type of Peters Anomaly. For the total number of patients, the VA results were LogMAR 1.71 ± 1.04. The results by groups were: Type I with only medical monitoring LogMAR 0.3 ± 0, Type I with only Optical Iridectomy (OI) LogMAR 0.97 ± 0.78, Type I with PKP LogMAR 1.22 ± 0.97, Type II without a compromised posterior pole with PKP LogMAR 2.41 ± 0.80, and Type II with a compromised posterior pole with PKP LogMAR 2.56 ± 0.48.ConclusionsThe result of VA and long-term corneal failure is directly related to the type of Peters Anomaly. Patients with Type I who only required medical follow-ups had the most favourable prognosis. Patients who underwent Peripheral Iridectomy followed and patients in which PKP was performed had an inferior prognosis.     

Papilitis y neurorretinitis de etiología tuberculosa

A 57-year-old man with miliary tuberculosis reported visual loss in his right eye, a month after starting a four-drug antituberculous treatment regimen. On exploration, an inferior segmental optic disc edema was objectived and it was attributed to ischemic aetiology. Ethambutol was withdrawn and 60 mg of oral prednisone daily were given with a tapering dosage. One and a half months later, he presented a sudden loss of vision in his left eye. In fundoscopy, a papillary edema accompanied by a foveal neurosensory detachment was observed but with no more accompanying uveitic signs. Treatment was intensified with moxifloxacin and corticosteroids were reduced, showing a resolution of the macular detachment but with optic atrophy.Isolated tuberculous involvement of the optic nerve may possible in the context of miliary tuberculosis. In this case, the adopted therapeutic approach to the initial papillitis, which was interpreted as ischemic, could favour the appearance of a neuroretinitis in the fellow eye.     

Evaluación de las secuelas clínicas y funcionales de la coriorretinopatía serosa central. Un análisis de serie de casos

ObjectiveTo evaluate the clinical and functional sequelae of patients with a diagnosis of resolved central serous chorioretinopathy (CSC), through macular OCT, contrast sensitivity test, visual field 10-2 and Farnsworth D-15 color test.Methods27 eyes of 26 individuals with CSC resolved by macular OCT were included and evaluated. The patients underwent a contrast sensitivity test with the Optec 6500 equipment, a 10-2 visual field with an Octopus 900 Haag-Streit, and a Farnsworth D-15 color test.ResultsSequelae were observed in 20 eyes (74.1%) by macular OCT and in 21 (77.8%) in contrast sensitivity, predominantly type 2 defect. Also 27 (100%) had a visual field 10-2 altered corresponding to reduced foveal sensitivity, 11 eyes (40.7%) corresponded to central and paracentral scotomas. The color test showed alteration in 11 (40.7%) of the total eyes evaluated, finding tritanomaly in 9 of them (81.8%). No significant differences were observed in the studies between observation group vs the treatment group.ConclusionsCSC can leave sequelae in the visual quality of patients despite treatment in the acute phase. Visual acuity before and after treatment in the intervention group had no significant difference.     

Cirugía monocular de 4 músculos extraoculares para la exotropía monocular de gran ángulo

IntroductionRecurrent exotropia is common following surgery for monocular large angle constant sensory exotropia. Surgery is usually limited to operations on the affected eye. Simultaneous oblique weakening surgery may enhance the effect of the horizontal rectus muscles surgery by decreasing the abducting forces. We report the results of simultaneous oblique muscle weakening procedures combined with ipsilateral horizontal rectus muscle surgery constant monocular exotropia greater than 35 prism diopters (PD).MethodsRetrospective case series of patients who underwent unilateral lateral rectus recession combined with medial rectus muscle resection and simultaneous weakening of both ipsilateral oblique muscles. Primary outcome measure was ocular alignment in primary position.ResultsTwelve eyes of 12 patients were included. The mean preoperative exotropia improved from 57.9 ± 15.1 (range 35–80; median 60 PD) to 3.3 ± 5.5 (range 0–16; median 0 PD) postoperatively (p < 0.005). Two (66%) patients with a pre-existing vertical deviation had resolution of their vertical misalignment postoperatively. At the last postoperative follow up 92% of the patients had an exodeviation of 10 PD or less (range 0–16 PD median 0 PD), and 7 (58%) measured near and distance orthotropia. Postoperative abduction measured −0.6 ± 1 (0 to −3) and adduction −0.4 ± 0.7 (0 to −2).ConclusionWeakening the ipsilateral oblique muscles may enhance the effect of the horizontal rectus muscles surgery by decreasing the abducting vectorial forces when operating for a large angle monocular exotropia. As an additional potential advantage, oblique muscle surgery may be used simultaneously to address associated vertical deviations.     

Retinopatía asociada a ocriplasmina: posible causa de fracaso de cierre de agujero macular

Case report

A 53 year-old woman with a stage 2 macular hole received ocriplasmin injection as a first approach. She subsequently underwent pars plana vitrectomy due to enlargement of the hole post-injection. The visual gain following the surgery was minimal despite closure of the hole. This could be explained by outer retina atrophy as a consequence of potential toxic mechanisms related to ocriplasmin.

Ranibizumab intravítreo en el tratamiento de membrana neovascular subretiniana en un caso de coroidopatía puntata interna

Case reportWe report the case of a 28-year old woman suffering loss of visual acuity in her left eye, who presented an image suggestive of a subretinal neovascular membrane in her left eye, and bilateral retinal lesions compatible with punctate inner choroidopathy (PIC). She was treated with intravitreal ranibizumab obtaining excellent results.DiscussionThe differential diagnosis must be made between PIC and the rest of “white dot syndromes” and the presumed ocular histoplasmosis syndrome (POHS). Antiangiogenic drugs may be a good alternative for the treatment of such diseases when they develop a subretinal neovascular membrane.     

Tendencias actuales de la cirugía de estrabismo en un hospital terciario

ObjectiveTo analyze the strabismus surgeries and the outcomes during a year and a half in a tertiary hospital.Material and methodsA retrospective study of patients who underwent strabismus surgery. The mean age, sex, diagnosis, diplopia, surgery, anesthesia, adjustable sutures, results, reoperations and follow up time from surgery were analyzed. A good outcome was considered when the final horizontal deviation was less than 10 prism diopters (pd) and the vertical deviation less than 5 pd without diplopia.ResultsA total of 153 cases were operated on, mean age: 43.14 ± 25.58 years (61.4%: women). 74.5% of patients were ≥ 18 years (33.33% ≥ 60). Diplopia was present in 51% of patients. The most frequent deviation was horizontal: 83.6%. The most frequent diagnosis was cranial nerve palsies: 32% (VI nerve: 12.4%), restrictive strabismus: 7.2%, and the aged related distance esotropia: 6.5%. Adjustable sutures were used in 19.7% of cases and topical anesthesia in 65.4%. Good outcomes was present in 79.2% of cases at the end of follow-up. Reoperations were needed in 25.5%. Follow-up evolution time was 11.87 months ± 6.5. The sex female (P = .012) and the oblique superior surgery (P =.017) were associated with bad outcome.ConclusionThe adult strabismus surgery was three times more frequent than the children strabismus surgery. The third of the adults that were operated on were ≥ 60 years. The cranial nerve palsies were the most frequent diagnosis. Adjustable sutures were rarely used. Good outcomes were obtained in most of the patients at the end of follow-up.

Case report

Bilateral Acute Iris Transillumination (BAIT) is a disease characterised by bilateral acute, severe pigment dispersion of the iris, and pupil sphincter paralysis. The case is reported of a 51-year-old female who was diagnosed with BAIT syndrome, with refractory ocular hypertension in the left eye, and who needed filtering surgery. Aqueous misdirection was developed a week after surgery, then pars plana vitrectomy was performed and the complication was solved.

Diagnóstico clínico y genético de un caso de síndrome de Meretoja e intervención mediante lifting frontotemporal

A 56-year-old male with family background of corneal dystrophy presents with poor subjective vision. Biomicroscopy reveals bilateral reticular stromal dystrophy and facial inspection shows signs of muscle dysfunction, such as eyebrow ptosis, weakness and sagging of the frontal muscles, redundant skin on the forehead and skin hyperelasticity.The patient is referred to plastic surgery for evaluation of the frontal muscle involvement, undergoing a frontotemporal lifting procedure. On the other hand, genetics confirms the pathogenic variant c.640G>A (p.Asp214Asn) in the GSN gene, encoding gelsolin, a mutation associated with Finnish-type familial amyloidosis or Meretoja syndrome.
