The authors investigated in a group of 850 patients the influence of long-term general corticotherapy on the transparency of the lens and intraocular pressure in relation to the length of therapy, dosage, age and sex of the patient. The presence of posterior subcapsular cataract was revealed in 5.2% of the patient, a raised intraocular pressure in 12.8%. The authors reached the conclusion that the duration of corticotherapy did not influence in a substantial way the development of posterior subcapsular cataract nor of cortisone glaucoma. A dose of 10-15 mg per day may be considered marginal for the development of cataract; dosage has no basic effect on the development of glaucoma. The maximum incidence of complications was in advanced age groups. No predisposition as regards sex was observed. A significant role in the development of cortisone cataract and cortisone glaucoma is played by individual sensitivity to corticoids.

Late presentation of Coats disease in a 12-year-old boy: a case report.
Pan Afr Med J
January 2025
Department of Ophthalmology, Faculty of Medicine Universitas Airlangga, Dr Soetomo Hospital, Surabaya, Indonesia.
Coats disease is a rare abnormality characterized with retinal telangiectasia and aneurysms with retinal exudation, most often seen in young males and usually affecting only one eye. A 12-year-old boy came in with a three-month history of vision loss and pain in his right eye, alongside progressively worsening blurred vision over the last year. His visual acuity was reduced to only light perception in the right eye, while his left eye maintained 5/5 vision.

St Paul's Eye Unit, Royal Liverpool University Hospital, Liverpool, UK.
Background: The post-operative evaluation of trabeculectomy blebs has traditionally relied on subjective clinical grading systems performed at the slit-lamp. This study explores the use of swept source anterior-segment optical coherence tomography (AS-OCT) to objectively measure bleb internal reflectivity and morphology, and to distinguish blebs with surgical success vs. failure.

J Control Release
January 2025
Department of Materials Science and Engineering, Pohang University of Science and Technology (POSTECH), 77 Cheongam-ro, Nam-gu, Pohang, Gyeongbuk 37673, Republic of Korea. Electronic address:
Although smart contact lenses have demonstrated great potential in theranostics, there remain critical challenges and opportunities in their commercial development. In this Perspective, the current status and capability of smart theranostic contact lenses are highlighted, focusing on their application as sensing systems for detecting biomarkers such as glucose, intraocular pressure (IOP), and inflammatory cytokines, and as drug delivery systems (DDS) for precise and controlled therapy. Additionally, key challenges associated with clinical development and commercialization of smart theranostic contact lenses are discussed, to optimize diagnostic and therapeutic interventions.

Department of Ophthalmology, Kangbuk Samsung Hospital, Sungkyunkwan University School of Medicine, Seoul, Republic of Korea.
Purpose: To investigate the heritability of genetic influence on macular choroidal vascularity index (CVI).
Methods: Total choroidal area (TCA), luminal area (LA), and CVI was measured using horizontal scan of spectral-domain optical coherence tomography with enhanced depth imaging in the 373 healthy twin participants. Characteristics of the participants were investigated, including age, sex, axial length, hypertension, diabetes, drinking habits, and smoking status.
Systemic TRPV4 inhibition worsens retinal response to acute intraocular pressure elevation in older but not younger mice.
Optom Vis Sci
January 2025
Department of Anatomy and Physiology, The University of Melbourne, Parkville, Victoria, Australia.
Significance: Previous evidence showed that transient receptor potential vanilloid 4 (TRPV4) inhibition was protective of retinal ganglion cell (RGC) loss after chronic intraocular pressure (IOP) elevation in young animals. However, the role of TRPV4 in mechanosensing IOP changes in the aging eye is not well understood.
Purpose: This study compared the recovery of retinal function and structure after acute IOP elevation in 3- and 12-month-old mouse eyes with and without TRPV4 inhibition.
