Incidence of conjunctival squamous cell carcinoma (cSCC) in Zimbabwe is >30-fold higher than the global average. cSCC risk is notably higher among people with human immunodeficiency virus, implicating impaired immune response and a yet unknown infectious etiology. Formalin-fixed, paraffin-embedded blocks from Zimbabwe, comprising conjunctival precancer (n = 78), invasive cSCC cases (n = 148) and nonmalignant eye lesions (n = 119), were tested for multiple DNA viruses using Luminex bead-based technology.

To combat the pandemic, measures such as face mask-wearing, hand-washing and -sanitizing, movement restrictions, and social distancing have been introduced. These measures have significantly disrupted education, particularly health professions education, which depends on student-patient contact for the development of clinical competence.

The University of Zimbabwe College of Health Sciences (UZ-CHS) has never had a formal ophthalmology training curriculum for medical graduates since its inception. This has cast doubts on the quality of medical graduates produced with regards to delivery of basic primary eye care in the community.

Traditional Eye Medicine (TEM) use may be associated with various ocular complications including blindness. A study on the prevalence of TEM use was carried out at Sekuru Kaguvi Hospital Eye Unit (SKHEU) in Harare, with emphasis on the types ofTEM used and associated ocular complications.

However, SCC has recently become an important clinical problem due the identification of a significantly high incidence of SCC among a group of black African patients with AIDS. However, basic research concerning SCC, including both intraepithelial and invasive squamous neoplasia, is limited due to the lack of an ocular tumor animal model.

We report a 4 months old infant with orbital rhabdomyosarcoma with poor outcome. Reluctance to use aggressive local control measures and suboptimal chemotherapy dosing are significant contributory factors.

Design: Retrospective study.
Methods: Analysis of data from the Zimbabwe National Cancer registry and records of patients admitted to the Paediatric Oncology unit.
Objective: To validate the use of finger counting (low level technology tool) in screening for blindness in the outpatients department of a tertiary eye unit with the view of employing the test for screening illiterate people in hard to reach parts of the country where the conventional visual acuity charts are not available.
Design: Aperformance evaluation of counting fingers (LLTT) in screening for blindness against the standard test (Snellen chart).
Setting: Sekuru Kaguvi Eye Unit, Parirenyatwa Hospital, Zimbabwe.
Four patients with bilateral ocular surface squamous neoplasia attended to at Sekuru Kaguvi Hospital Eye Unit are being presented to alert practitioners that OSSN is potentially a bilateral disease and its prevalence is likely to increase as the life expectancy of HIV infected patients is being positively affected by antiretroviral therapy. Reports on ocular diseases should be clear on laterality to avoid confusion between number of patients affected and number of eyes involved since the two cannot be used interchangeably.

Patients And Methods: Twelve patients with XP were seen over a 25-year period, and were retrospectively reviewed for age, gender, clinical features, treatment, and follow-up.
Results: There were 8 females and 4 males with an age range of 3 to 18 years.
Objective: To review and determine the attributed causes of deaths among patients who died in Sekuru Kaguvi Hospital (SKH) Eye Unit Wards between August 1984 and October 2008
Study Design: Retrospective study of completed BD12 forms and case records of inpatients who died betweenAugust 1984 and October 2008.

Results: Eighty three deaths occurred in the unit during the 24 year period, 51% were females and 33.
Introduction: Anecdotal and published reports suggest that ocular tumours are on the increase in Zimbabwe.
Objectives: To determine the trends in incidence rates of common malignant ocular tumours registered with the Zimbabwe Cancer Registry during the last decade (1990 to 1999).
Design: Retrospective study.
Objective: To determine the extent of association and relative risk of developing ocular surface squamous neoplasia (OSSN) among HIV positive patients seen in July 2004 at Sekuru Kaguvi Eye Unit, in Harare, Zimbabwe.
Design: Prospective study.
Setting: Sekuru Kaguvi Eye Unit.
Objectives: To determine the rate of and indications for enucleation at Sekuru Kaguvi Eye Unit (SKEU) in Zimbabwe and compare the findings with those from other tertiary eye care centres in the developing world.
Design: Descriptive retrospective cross sectional study.
Setting: Sekuru Kaguvi Eye Unit, Parirenyatwa Hospital, Harare, Zimbabwe.
Objective: To determine the trend in the prevalence of ocular surface squamous neoplasia (OSSN) among ocular surface tumour biopsies submitted for histology from Sekuru Kaguvi Eye Unit (SKEU), Harare between January 1996 and August 2000.
Design: The study was a retrospective records review of patients who had biopsies of ocular surface tumours done during the study period.
Setting: National Referral Centre for eye patients (Sekuru Kaguvi Eye Unit), Parirenyatwa Hospital, Harare, Zimbabwe.

Design: Retrospective cross sectional study.
Setting: Department of Surgery, Parirenyatwa Hospital, University of Zimbabwe.
A case of extreme myopia causing remedial blindness in a child enrolled at a school for the blind is presented. The need for training optometrists and creating posts for them at Central and Provincial Eye Units in the country has been highlighted. Selection guidelines for enrolling students at schools for the blind are essential if inappropriate admissions to these schools are to be curtailed.

The adoption of extracapsular cataract extraction and implant surgery as the standard method of managing senile cataracts in Zimbabwe has been hindered by several factors. These are; succumbing to pressure from promoters of intracapsular cataract surgery, inadequate human and material resources and the problems related to implementation. The problems with intracapsular cataract surgery and aphakic correction are well known.
