Retinoblastoma chemotherapeutic drugs and their toxic effects on RPE cells

There is reported clinical evidence of retinal pigment epithelium (RPE) alterations after intra-arterial (IAC) and intravitreal chemotherapy (IViC) of retinoblastoma. The purpose of this study was to investigate the cellular toxic effects of melphalan, topotecan and carboplatin on the RPE...

Choroidal and RNFL thickness in patients with OSAS

In obstructive sleep apnoea syndrome (OSAS), hypoxia secondary to repetitive apnoeic episodes leads to blood pressure variations and haemodynamic changes. There is also intermittent activation of the sympathetic system when the patient is aroused from sleep during apnoeic episodes. OSAS...

Macular thickness and visual fields

The authors describe a comparison of spectral domain OCT with Humphrey visual fields (HVF) mean deviation (MD) and pattern standard deviation (PSD), examining the retinal thickness of the macula and circumpapillary retinal nerve fibre layer (RNFL) defects. Seventy-three subjects who...

Triamcinolone (TA) deposits following subcutaneous injection to treat chalazion

Chalazia are chronic lipogranulomatous inflammations of the eyelid secondary to a blocked meibomian gland. Whilst most resolve spontaneously, certain chalazia warrant treatment. Options include incision and curettage (I&C), lesion excision, intralesional steroid injections, and botox injections [1]. I&C is usually...
