To evaluate the prevalence of dry eye disease (DED) after cataract surgery, and the impact of hyaluronic acid and ginkgo biloba eyedrops (HA-GB). Forty patients with no DED received Ocular Surface Disease Index (OSDI) questionnaire, assessment of conjunctival hyperemia and epithelial damage, fluorescein tear break-up time (TBUT) at baseline, day 1, week 1, and 4; adherence and tolerability were checked at weeks 1 and 4. At day 0 patients underwent cataract surgery and were randomized to standard postoperative care (control group) or standard postoperative care + HA-GB 3 times a day for 4 weeks (HA-GB group).

In the homeostasis of the ocular surface, vitamins play a critical role in regulating inflammatory responses and promoting cell differentiation, development and correct function. Systemic vitamin supplementation has been available for many decades; in recent years, thanks to pharmacological advancements, topical vitamin delivery has also become available in an attempt to better treat ocular surface disease (OSD) and dry eye disease (DED). In this paper, we reviewed the current evidence on the role of vitamin supplementation in OSD and DED.

Purpose: The purpose of this study was to investigate the efficacy and safety of surgically induced macular detachment (MD) for the treatment of refractory full-thickness macular hole (FTMH).

Materials And Methods: Clinical data were age, gender, lens status, and best corrected visual acuity (BCVA). Preoperative tomographic parameters were: FTMH morphology (intraretinal cyst and elevated or flat edges) and FTMH diameter.

Purpose: The purpose of this study is to describe spectral domain-optical coherence tomography and autofluorescence images in a case of bilateral Purtscher-like retinopathy.

Methods: This is an observational case report of a 31-year-old man suffering with Purtscher-like retinopathy postpancreatitis.

Results: In the acute phase, spectral domain-optical coherence tomography showed hyperreflectivity in the inner retinal layers, corresponding to cotton-wool exudation as a result of precapillary ischemia.

Purpose: The purpose of this study was to compare and evaluate artifact errors in automatic inner and outer retinal boundary detection produced by different time-domain and spectral-domain optical coherence tomography (OCT) instruments.

Methods: Normal and pathologic eyes were imaged by six different OCT devices. For each instrument, standard analysis protocols were used for macular thickness evaluation.

Purpose: To describe the spectral-domain optical coherence tomography (SD-OCT) findings in a patient with a premacular hemorrhage due to Valsalva retinopathy treated with Nd:YAG laser.

Methods: Serial SD-OCT examinations were performed before and after Nd:YAG laser treatment to identify the cleavage plane of blood accumulation, as well as the exact location of the areas targeted by the laser spots and the different involvement of the affected retinal layers.

Results: The SD-OCT scan above the level of settled blood showed that the cleavage plane was located under the internal limiting membrane (ILM).
