Descemet's membrane substrate from human donor lens anterior capsule

Background: To study the potential use of human donor anterior lens capsule as a Descemet's membrane substrate. Methods: Anterior lens capsules were recovered from the lenses of 30 cornea donors. Human corneal endothelial cells were recovered from the remaining corneal sclera rims of 15 donor corneas used for penetrating keratoplasty. Samples were sorted into three groups. Group 1 consisted of 10 samples in which the endothelial cells were allowed to grow on anterior lens capsules. In Group 2 human corneal endothelial cells grew on a collagen membrane and in Group 3 on polystyrene culture plates. Cell density, morphology and adherence of the cell–capsule complex were evaluated at 1, 4, 7 and 14 days with a phase‐contrast microscope, a scanning electron microscope and by histology. Cell viability was quantified by a microscopic live–dead assay. Expression of zonula occludens‐1, Na⁺/K⁺‐adenosine triphosphatase, tissue transglutaminase and vimentin were investigated by immunohistochemistry. Results: A mean diameter of 10.05 ± 0.13 mm of anterior capsule was obtained as a substrate for cell culture. Endothelial cell density of Group 1 was measured at 2455.4 ± 283.8 cells/mm², which was also comparable with the cell density of the control group. Cell viability was 95% or superior in all groups and multiple cellular interconnections developed between growing cells. Immunohistochemical analysis demonstrated strongly positive staining for all investigated proteins. Electron microscopy confirmed the adherence and monolayer growth of the endothelial cells. Conclusions: Human donor anterior lens capsule might therefore be a potential scaffold for the ex vivo expansion of human corneal endothelial cells.     

Anatomy of Tenons capsule

Background: The microscopic and macroscopic anatomy of the anterior and posterior Tenons capsule is described. Methods: An observational anatomic study of twelve orbits of 6 cadavers (mean age 79.5 years) were examined microscopically and 8 orbits of 4 cadavers (mean age 76.8 years) were examined macroscopically. After orbital exenteration, an X‐shaped incision was made in the specimens to include the posterior part of the globe. The sections were divided into four parts: superomedial; inferomedial; superolateral; and inferolateral. In the macroscopically examined specimens, the eyelids and globes were removed from the exenterated tissues and the appearance of Tenons capsule was studied. Results: In the microscopic study, Tenons capsule covered the sclera beneath the conjunctiva and contained smooth muscle fibres in the anterior area. This anterior fascia, which had a thick appearance, reached the globe equator. From there, the capsule of the orbital fat, which contained no smooth muscle fibres, enveloped the sclera and reached the optic nerve. This was defined as the posterior capsule. In the macroscopic specimens, Tenons capsule had a thick and fibrous white appearance in the anterior area. More posteriorly, the capsule was thinner and more translucent. This thin capsular part was generally larger in the lateral area than in the medial area. Conclusions: Tenons capsule is composed of an anterior thick fibrous tissue comprising the orbital smooth muscle network and the posterior thin fibrous capsule of the orbital fat.     

Polymethyl methacrylate intraocular lens opacification 20 years after cataract surgery: A case report in a tertiary eye hospital in Saudi Arabia

Snowflake degeneration is a slow progressive opacification of polymethyl methacrylate (PMMA) intraocular lenses (IOLs). This late postoperative complication can occur a decade or later after implantation. The deposits are composed of IOL materials that tend to aggregate centrally. There is a relative paucity of the literature on snowflake degeneration of IOLs. Symptoms can range from mild visual disturbance to significant loss of visual acuity. In cases of opacification after IOL implantation, the different diagnosis should include snowflake degeneration to prevent surgical intervention such as lens exchange or explantation unless clinically warranted. We report a case of late optical opacification of a PMMA IOL, the clinical diagnosis and treatment that increased best corrected vision.
