Association of Postfungal Keratitis Corneal Scar Features With Visual Acuity.

Importance: Corneal opacity is a leading cause of visual impairment worldwide; however, the specific features of corneal scars, which decrease visual acuity, have not been well characterized.

Objective: To investigate which features of a postfungal keratitis corneal scar contribute to decreased visual acuity after an episode of infectious keratitis and evaluate whether any corneal features may be used as outcomes for clinical trials.

Design, Setting, And Participants: In this ancillary, prospective cross-sectional study, a subset of study participants treated for fungal keratitis (n = 71) as part of the Mycotic Ulcer Treatment Trial I (MUTT I) underwent best spectacle-corrected visual acuity (BSCVA) and best contact lens-corrected visual acuity examination, Scheimpflug imaging, and anterior segment optical coherence tomography at a referral hospital in India approximately 2 years after enrollment.

Repeatability and Reproducibility of Slit Lamp, Optical Coherence Tomography, and Scheimpflug Measurements of Corneal Scars.

: To determine the repeatability and reproducibility of anterior segment optical coherence tomography (AS-OCT) and Scheimpflug photography for several measurements of corneal scars, including scar size, scar depth, and corneal thickness. : A series of patients treated for fungal keratitis at a tertiary eye care center in South India were recalled two years after successful treatment. Eyes with corneal scars had a slit lamp examination performed by two ophthalmologists masked to the other's examination.

Automated Segmentation Errors When Using Optical Coherence Tomography to Measure Retinal Nerve Fiber Layer Thickness in Glaucoma.

Purpose: To characterize the error of optical coherence tomography (OCT) measurements of retinal nerve fiber layer (RNFL) thickness when using automated retinal layer segmentation algorithms without manual refinement.

Design: Cross-sectional study.

Methods: This study was set in a glaucoma clinical practice, and the dataset included 3490 scans from 412 eyes of 213 individuals with a diagnosis of glaucoma or glaucoma suspect.

Risk Factors for Return to the Operating Room after Resident-Performed Cataract Surgery.

Objective: Investigate risk factors for unplanned return to the operating room after resident-performed cataract surgery.

Design: Retrospective case-control study.

Setting: Institutional.

Ex-PRESS outcomes using mitomycin-C, Ologen alone, Ologen with 5-fluorouracil.

To compare the complication rate and effectiveness of mitomycin C (MMC), Ologen alone, and Ologen with 5-fluorouracil (5-FU) as adjunctives with Ex-PRESS mini shunt for medically uncontrolled glaucoma. Retrospective comparative study of 59 Ex-PRESS mini shunt trabeculectomy operations coupled with Ologen implantation alone, transient MMC application or Ologen implantation with 5-FU as adjunctive treatment. Eight eyes (7 patients) received Ologen alone, 37 eyes (34 patients) received MMC, and 14 eyes (14 patients) received Ologen with 5-FU as adjunctive therapy.

Papillary cystadenocarcinoma of the lacrimal gland after radiation for bilateral retinoblastoma.

The authors report a case of papillary cystadenocarcinoma of the lacrimal gland after irradiation for bilateral retinoblastoma. A 32-year-old man with a history of bilateral retinoblastoma, diagnosed shortly after birth, was treated with enucleation of the OS and a single session of radiation to the OD. Over 30 years later, he presented with an orbital mass of the right lacrimal gland that on biopsy demonstrated papillary cystadenocarcinoma.

Technique for shortening a long clear corneal incision.

An optimal clear corneal incision creates a self-sealing intrastomal tunnel. Variability in incision length may pose surgical difficulties for subsequent phacoemulsification. An incision that is too long may lead to challenges including decreased instrument mobility, decreased visibility due to corneal striae, stromal hydration, and a difficult angle of approach to the cataract.
