This study concludes:
Hormone replacement therapy in postmenopausal women does not significantly affect refractive status, corneal topography, and wavefront aberrations of the eye at 6-month follow-up.

According to this report:
14% of patients treated surgically experienced a "reversal of cupping" compared with just 1% of patients treated medically.
It may become standard in the future to monitor patients on Plaquenil using OCT.

According to this paper:
Systemic treatment with bevacizumab improved vision and reduced lesion sizes in a small study of patients with pigment epithelial detachment secondary to age-related macular degeneration.
According to this study:
FDT and SWAP detect functional losses in cases of suspected glaucoma before glaucomatous losses detected by standard perimetry.

"Gonioscopy is an essential tool for making an accurate diagnosis and understanding the biological mechanisms at work in glaucoma suspects, according to a specialist speaking here at the OSN Las Vegas meeting"
Mean VA improved by at least two lines in 37% of patients.
Conclusion: PPV with ILM removal appears to be effective in reducing DME and improving visual acuity, and its effectiveness is maintained in the long term. Recurrence of DME may be observed in the late postoperative period.

No association was detected between short- and medium-term use of antithyroids, thyroid hormones, and thiazide diuretics and the risk of AMD. Short- and medium-term use of antacids seems to be associated with a small increase in the risk of this disease. However, this increased risk is likely the result of residual confounding by smoking or uncontrolled confounding resulting from socioeconomic status. No conclusions could be drawn regarding longer-term use of each drug category.

Significant improvements in best-corrected VA after 1 month and their maintenance over a 3-month period were observed after verteporfin PDT combined with intravitreal bevacizumab (Avastin).

From the paper:
There is evidence suggesting that visual disturbances in patients with Alzheimer’s Disease (AD) are due to pathologic changes in the retina and optic nerve, as well as to higher cortical impairment.
Conclusion: Retinal abnormalities in early AD include a specific pattern of RNFL loss, narrow veins, and decreased retinal blood flow in these veins.

According to this study:
Dorzolamide, in association or in fixed combination with timolol, significantly improves retinal blood flow in JPOAG patients.
Perhaps we can look forward to neuroprotective results generally as well. I look forward to the studies.
There were no consistent associations with the amount of beer, wine, or liquor consumption and the incidence or progression of AMD. Alcohol consumption is unlikely to strongly increase (or decrease) the risk of AMD.

The RNFL showed a stronger structure–function association and a higher diagnostic sensitivity for glaucoma detection than did the neuroretinal rim.
"Most ophthalmologists are aware of the risk of elevated intraocular pressure developing 1 or 2 months after an intravitreal injection of triamcinolone. However, the two cases reported here demonstrate that such a rise can occur significantly later than this. All patients who have had intravitreal steroid injection should therefore have prolonged intraocular pressure monitoring. "
Advanced Medical Optics is voluntarily recalling its Complete MoisturePlus contact lens solutions in response to data from the U.S. Centers for Disease Control and Prevention showing an increased risk of Acanthamoeba keratitis associated with its use, the company announced.
