2GB Afternoons: Protecting Your Sight: Ocular Health with Dr Neil Sharma
June 2025 | Presenter: Lucy Zelic
Featured discussion
Modern treatment options for macular degeneration and the significant impact of uncorrected refractive errors in children
Topics discussed
-
Leading causes of vision loss across age groups: Uncorrected refractive errors in children and adolescents, and the prevalence of diabetic retinopathy as a primary cause of permanent vision impairment in the 20 to 60 working-age demographic.
-
Age-related eye conditions: The vulnerability of the elderly population to conditions like glaucoma, cataracts, and macular degeneration, and how vision loss impacts independent living.
-
Cataract surgery and timing: Understanding cataracts as a natural clouding of the lens, and identifying when it is visually significant enough to warrant highly successful corrective surgery.
-
Screen time management: Strategies to alleviate ocular strain from digital devices, including the 20-20-20 rule, regular short breaks to promote blinking, and managing late-night screen exposure.
-
Nutritional support for eye health: The roles of vitamins A, C, and E, alongside antioxidants like lutein and zeaxanthin, found in green leafy vegetables, oily fish, and nuts to preserve macular health.
-
Preventative ocular protection: The long-term importance of proper UV sun protection to minimize skin cancers and ocular melanomas around the eye, and the critical use of safety glasses during home renovations to avoid ocular trauma.

2GB Afternoons JulEYE Interview with Dr Neil Sharma
July 2024 | Presenter: Michael McClaren
Featured discussion
The critical importance of early detection and proactive screening for preventable eye diseases, the insidious nature of glaucoma, and clarifying common public inquiries regarding astigmatism and cataract surgery.
Topics discussed
-
The Stealth Progression of Glaucoma: Explaining glaucoma as progressive, asymptomatic damage to the optic nerve that quietly degrades peripheral vision. Because human visual fields overlap, individuals rarely notice early deficits until severe "tunnel vision" sets in, making timely clinical screening essential before permanent vision loss occurs.
-
Proactive Public Health Interventions: Emphasizing that up to 90% of blindness and visual impairment in Australia is preventable or treatable if caught early, necessitating routine comprehensive checkups even in the absence of noticeable symptoms.
-
Demystifying Astigmatism: Outlining astigmatism as an asymmetrical curvature of the refractive surface of the eye. Using the analogy of a spherical soccer ball versus an elongated rugby or AFL ball, Dr. Sharma noted that this structural variance focuses light unevenly, causing blurred vision that often may be success corrected with spectacles, contact lenses, or laser/lens-based refractive procedures.
-
Cataracts and Associated Systemic Conditions: Evaluating a query from a 49-year-old patient with rheumatoid arthritis suffering from recurrent iritis (intraocular inflammation). Dr. Sharma clarified that both chronic iritis and the prolonged use of corticosteroid eye drops can accelerate cataract formation, requiring corrective surgery even in younger age groups if visual symptoms impair daily activities.

2GB Afternoons: World Glaucoma Week Interview with Dr Neil Sharma
March 2024 | Presenter: Michael McClaren
Featured discussion
The sneaky and asymptomatic nature of glaucoma, the critical importance of early diagnostic scanning before permanent damage occurs, and a global look at how this irreversible condition impacts millions of families worldwide.
Topics discussed
Focus on glaucoma, including :
-
Asymptomatic Peripheral Field Loss: Glaucoma stands as a leading cause of irreversible blindness that systematically destroys peripheral vision without early noticeable symptoms because the visual inputs of both eyes subtly overlap.
-
Frontline Screening Interventions: Because noticeable changes like "tunnel vision" only manifest once profound, irreversible optic nerve damage has occurred, objective eye health screening every 1 to 2 years is vital for everyone over 40.
-
Genetic and Modifiable Risk Factors: A family history of glaucoma in a first-degree relative elevates an individual's personal risk tenfold, meaning managing modifiable factors like intraocular pressure (IOP) is key to slowing progression.
-
Sustainability of Topical Drop Therapy: For the vast majority of patients, simple adherence to daily prescription eye drops or localised laser procedures in many patient successfully stabilises intraocular pressures to protect long-term sight.
-
Anatomic Risks for Angle-Closure Glaucoma: Angle-closure glaucoma typically develops as the internal crystalline lens naturally thickens with age, creating an anatomical crowd that can trigger sudden, painful spikes in eye pressure.

2GB Nights: Presbyopia, Refractive Interventions, and Retinal Advancements Interview
October 2023 | Presenter: John Stanley
Featured discussion
The structural classification of cataracts, the universal onset of presbyopia, multi-focal and EDOF lens implants, and the ongoing evolutionary changes in medical retina therapy.
Topics discussed
-
Lifespan Distribution of Ocular Pathologies: Classifying common benchmarks where unique structural or refractive shifts afflict different age groups—noting that juvenile or congenital anomalies often present in childhood, diabetic retinopathy often emerges in middle age, and structural degenerative pathologies like glaucoma, cataracts, and age-related macular degeneration (AMD) dominate the demographic over 60 years.
-
The Universality of Presbyopia: Tracking a personal narrative from the host regarding his path from clear distance focus to developing text blur in his early 40s. Dr. Sharma characterized this as presbyopia—a natural ageing phenomenon where the internal crystalline lens becomes progressively rigid and less compliant.
-
Clear Lens Extraction and Intraocular Innovation: Dr. Sharma detailed the use of multifocal intraocular lenses and more recent Extended Depth of Focus (EDOF) lenses. The Monovision Strategy: Detailing the refractive concept of monovision, where a patient's dominant eye is surgically corrected for distance accuracy while the non-dominant eye is targeted for reading focus.
-
Discussion regarding the use of eye injections for the treatment of wet macular degeneration and advancements in retinal imaging including high-resolution scanning (OCT).
-
Urging listeners to access Australia's widespread eye care infrastructure for regular eye checks, especially if visual symptoms, a family history of eye disease and for children and those aged over 40 years.
-
Preventative Ocular Protection and UV Risk: Emphasizing the importance of proper sun protection to combat Australia's elevated rates of sun-related eye diseases and periocular skin cancers for adults and children.

2GB Afternoons: Tuesday Check-Up with Dr Neil Sharma
March 2023 | Presenter: Deborah Knight
Featured discussion
Host Deborah Knight highlights that World Glaucoma Week serves as a critical prompt for routine eye checkups, as roughly half of the estimated 300,000 Australians living with the condition are unaware they have the conditon.
Topics discussed
-
Glaucoma targets and damages the optic nerve, initially causing a progressive loss of peripheral vision. Because an individual's visual fields overlap, the brain dynamicially compensates for early deficits, meaning noticeable "tunnel vision" manifests once profound, irreversible damage has occurred.
-
Congenital Forms of Glaucoma: While the risk of developing glaucoma increases with age, it can also present as a rare congenital condition. This means some newborns are born with the disease and must navigate it as a lifelong challenge.
-
Sturge-Weber Syndrome and Intractable IOP: Dr. Sharma addressed a listener's query regarding his 25-year-old daughter, who has glaucoma secondary to Sturge-Weber syndrome.
-
Spectacle and Patching Interventions for Strabismus: Responding to a query regarding a 6-year-old child with crossed eyes (strabismus) in the Philippines, Dr. Sharma noted that while spectacles with prisms or surgery may correct alignment, patching the dominant eye is often crucial.
-
Presbyopia and Premium Intraocular Lens Tech: Reflecting on a caller's previous laser refractive treatment, Dr. Sharma noted that age-related reading decline (presbyopia) is a natural change to the lens . Dr Sharma discusses modern multifocal or EDOF implants to reduce the need for reading glasses.
