Purpose: To determine the ability of the photopic negative response (PhNR) of the uniform field electroretinogram (UF-ERG) to identify early glaucomatous changes in comparison to the checkerboard and bar stimuli of the pattern electroretinogram (PERG).
Methods: Forty-nine glaucoma patients were classified into two groups: glaucoma-suspect (23 eyes) and early to moderate glaucoma (30 eyes), based on their clinical examination and the results of standard automated perimetry. Thirty patients (30 eyes) with intraocular pressures (IOP) of 21 mmHg or less, with no history of reported high IOP, were included as controls.
Purpose: To evaluate the effect of tobacco smoking on trabeculectomy outcomes.
Methods: Charts of patients with glaucoma who underwent trabeculectomy performed by a single surgeon between 2007 and 2016 were retrospectively reviewed. Charts were screened for a documented history of smoking status before surgery.
Purpose: To compare 1-year outcomes of illuminated microcatheter-assisted circumferential trabeculotomy (IMCT) vs conventional partial trabeculotomy (CPT) for primary congenital glaucoma (PCG).

Methods: Forty eyes of 31 patients with unilateral or bilateral primary congenital glaucoma aged less than 2 years were randomized to undergo IMCT (20 eyes) or CPT (20 eyes).
Cornea transplantation has a high success rate and typically only requires topical immunomodulation. However, in high-risk cases, systemic immunosuppression can be used. We conducted a systematic review on the efficacy and side effects of systemic immunosuppression for high-risk cornea transplantation.

Methods: This retrospective study included 100 cases of primary adult onset glaucoma. IOP readings obtained with Goldmann applanation tonometry between 7 am and 10 pm were compared to office-hour readings.
Purpose: To evaluate the impact of initial topical medical therapy on newly diagnosed glaucoma patients using the Indian Vision Function Questionnaire (IND-VFQ33).

IND-VFQ33 is a 33 item QoL assessment tool with three domains: General functioning, psychosocial impact and visual symptoms.
Purpose: To evaluate the test-retest variability of spectral-domain optical coherence tomography (OCT) in measurement of retinal nerve fiber layer (RNFL) thickness and macular ganglion cell-inner plexiform layer (GCIPL) thickness.
Methods: A total of 65 eyes of healthy subjects were enrolled in this observational cross-sectional study. RNFL thickness and GCIPL thickness were measured using the repeat scan optic cube and macular cube protocol using Cirrus HD-OCT (software version 6.
Purpose: To report the feasibility and outcome of lens aspiration, and Fugo blade-assisted capsulotomy and anterior vitrectomy in eyes with anterior persistent hyperplastic primary vitreous (PHPV).
Materials And Methods: In this case series, 10 eyes of 10 patients with anterior PHPV underwent lens aspiration. The vascularized posterior capsule was cut with a Fugo blade (plasma knife) and removed with a vitrector.
Purpose: To report the recognition and management of intra-Descemet membrane air bubble (IDMA) as a complication of big-bubble deep anterior lamellar keratoplasty (DALK).
Methods: IDMA was present intraoperatively in 8 eyes after DALK. Indications for surgery were healed keratitis (n = 4), macular dystrophy (n = 2), and keratoconus (n = 2).
The study was conducted to evaluate the intra-session repeatability of Tonopen AVIA (TPA). 180 eyes of 180 patients (50 eyes with glaucoma, 130 eyes of controls) were recruited for this observational study. The mean age of patients enrolled in the study was 43.

Consecutive cases with primary open-angle glaucoma (POAG) or primary angle-closure glaucoma (PACG) attending the outpatient services were evaluated for the presence of DM and HT and any systemic/ocular medications being taken were recorded. Of 615 glaucoma cases evaluated, 281 (45.

Methods: Fifty-five primary caregivers of children diagnosed with primary congenital glaucoma were evaluated. The magnitude of burden on caregivers was assessed using a Caregiver Burden Questionnaire (CBQ).
Purpose: To report the visual and refractive outcomes in an initial series of eyes undergoing femtosecond laser cataract surgery with implantation of a diffractive multi-focal intraocular lens (IOL).
Methods: The first 61 consecutive eyes undergoing femtosecond laser cataract surgery and ReSTOR (Alcon Laboratories Inc) +3.00-diopter (D) add IOL implantation between May and July 2011 were enrolled in the study (LCS group).
Objective: To report the surgical outcomes and safety of femtosecond (FS) laser cataract surgery (LCS) with greater surgeon experience, modified techniques, and improved technology.
Design: Prospective, interventional case series.
Participants: Fifteen hundred consecutive eyes undergoing FS laser cataract and refractive lens exchange surgery in a single group private practice.
Purpose Of Review: The introduction of the femtosecond laser to the field of cataract surgery offers many potential benefits. The femtosecond laser is able to perform three important steps in cataract surgery: capsulotomy, lens fragmentation and corneal incisions. Although evidence in support of its efficacy is accumulating, there is a surgical learning curve that needs to be addressed.

Design: Retrospective case series.
Methods: A review of patients undergoing intracorneal segment exchange was conducted.
Purpose: To evaluate outcomes of trabeculectomy with use of a subconjunctival biodegradable collagen implant (Ologen) combined with mitomycin C (MMC).
Methods: This retrospective study included 33 eyes of 24 patients with primary open-angle glaucoma who underwent fornix-based trabeculectomy with subconjunctival Ologen implant and MMC (0.1 mg/mL×1 min) between October 2008 and April 2010.
The recent introduction of femtosecond lasers to cataract surgery has generated much interest among ophthalmologists around the world. Laser cataract surgery integrates high-resolution anterior segment imaging systems with a femtosecond laser, allowing key steps of the procedure, including the primary and side-port corneal incisions, the anterior capsulotomy and fragmentation of the lens nucleus, to be performed with computer-guided laser precision. There is emerging evidence of reduced phacoemulsification time, better wound architecture and a more stable refractive result with femtosecond cataract surgery, as well as reports documenting an initial learning curve.

We report a case of recalcitrant microbial keratitis after epipolis laser-assisted in situ keratomileusis (epi-LASIK) surgery caused by Pseudomonas aeruginosa and review the literature on resistant Pseudomonas keratitis after excimer laser surgery. Microbial keratitis occurred two weeks after epi-LASIK surgery and was resistant to fluoroquinolones, aminoglycosides and macrolides but sensitive to meropenem. The patient had total corneal melting and required therapeutic penetrating keratoplasty.
