1. Minimum rim width (MRW) as measured by Spectralis OCT offers a novel method of measuring neural rim loss in glaucoma. A study in Central India revealed the greatest rim loss to be in the inferotemporal and superotemporal quadrants of the ONH. MRW requires further evaluation in early diagnosis and estimating progression in persons with glaucoma.

2. The Hooghly River Glaucoma Study, a population-based study conducted in West Bengal, India revealed the prevalence of glaucoma in the urban population (3.23%, CI 3.5-4.1) was higher than that in the rural counterpart (2.7%, CI 1.09-4.31). The study also observed that PACD is more common in this region of eastern India and recommends inclusion of gonioscopy in the comprehensive eye examination as part of early glaucoma detection and management.

3. Abnormal anatomical variations in pediatric eyes with shorter axial-length. Morphologic changes in eyes with short axial length following congenital cataract surgery, such as characteristic anterior and ciliary body development anomalies including elongated ciliary processes, abnormal insertion of ciliary body to posterior iris and flat pars plicata, high iris insertion and ill-defined anterior chamber angle structures observed by UBM were positively correlated with elevated intraocular pressures.

4. Relevance of ocular perfusion dynamics in glaucoma. Ocular perfusion pressure is crucial in maintaining the health of the optic nerve head. A decrease of ocular perfusion pressure below 40 mmHg increases likelihood of progression of glaucoma six-fold. Caution is advised in the use of beta blockers since these drugs can adversely affect nocturnal perfusion pressures with progression of glaucoma despite adequate IOP control.

5. Cerebrospinal fluid pressure ‒ Potential implications for glaucoma. Changes in IOP, Cerebrospinal fluid pressure (CSFP), or trans lamina cribrosa pressure difference (TLCPD) can be associated with a disturbance of homeostasis of the optic nerve head. In particular, glaucomatous optic neuropathy may be due to either an elevated IOP and/or an abnormally low orbital CSFP, or due to a change in the time-dependent relationship between the pulse-synchronous changes in IOP and orbital CSFP.

6. A novel outreach program using a portable fundus camera for glaucoma screening. In community screening employing portable fundus photography as against conventional direct ophthalmoscopy in Southern India, glaucoma referral was observed to be twice as frequent, validating the potential role of low cost portable fundus photography in glaucoma detection in comprehensive eye screening.

7. Aurolab Aqueous Drainage Device, a cost-effective non-valved tube developed for use in lesser developed communities has proved to be safe and effective for use in management of refractory glaucoma and long-term results of the device are awaited. (George V. Puthuran, Madurai, India)
